AWNING.

SPECIFICATION forming part of Letters Patent No. 328,921, dated October 27, .1885.

Application tiled J' une 8, 1885. `Se1ial No. 167 927.

To all whom, if may concern:

Beit known that I, EGBERT O. Coon, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Awnings, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figurel is a sectonal elevation of an awning, part of the frame being represented as broken away in order more clearly to illustrate the same. Fig. 2 is a sectional detail representing the extensible part of the frame; and Figs. 3 and 4 are representa tions like l and 2, respectively, excepting that they show a modification in the construction of the eXtensible part of the frame.

Like letters of reference indicate like parts.

Heretofore an objectionable circumstance relating to awnings has been that the wind would often cause the extension bars or rods of the frame to move sufficiently to produce a disagreeable rattling noise; another objection has been that when the awning was raised or drawn up on the fixed rods or guides forming frequently a part of the means for attaching the awning to the building, the folds of the canvas would frequently prevent the awning from being lowered without considerable trouble, and the said slides would frequently stick on said rods or guides.

The purpose of my invention is to avoid these objectionable features, and I will now describe the means which I employ for that purpose.

A! represents a Window frame. B B are pulleys in a fixed block, a, applied to the upper part of the frame A. C is a cleat, and D is a lug, both of which are applied to the said frame. E is the awning-frame, which, in the example shown, consists of a front bar or rod, and of two or more extension bars or rods, only one of which, c, is shown. F F are cords connected to the front bar and passing over the pulleys B B. G is the canvas. 'Ihe eX- tension-bars are connected to the front bar, and hinged or jointed to the lugs D D.

I may state, briefly, that the awning shown, as thus far described, is made and applied as has heretofore been common.

I also desire to state that my invention relates, chiefly, to the extension bars o'r rods, and

(No model.)

it is by means of my improved construction thereof that I am enabled to attain the results desired and already referred to. These novel features of construction I will now proceed to describe with sufficient particularity to enable those skilled in the art to which my invention appertains to reduce the same to practical use.

As shown in Figs. 1 and 2, the extensionbars are composed of three parts-a rod, d, a rod, d, and a tubular part or sleeve, 0l. The rods d and d both enter the sleeve d, one entering one end, and the other entering the other end; but these rods do not meet in the said tube, a considerable space or distance eX-V isting between their ends, as is clearly shown in the figures last above referred to. The inner ends of these rods I connect by means of a close spiral spring, e, and I also connect the rod d to the sleeve. This I do in the example shown by carrying the outer end of the spring e through an eye in the inner end of the rod d, and also through a hole in the sleeve d, and by tying the said parts together by means of the wire constituting the spring, as indicated at f, Fig. 2; but this connection may be made in any suitable or well-known way; or the particular means there shown may be varied, and are not an absolutely essential feature of my invention. G is a bead or annular rib on the outer side of the sleeve d, at the inner end thereof, and H is a cord by means of which the canvas is secured to the beaded end of the sleeve at a point between the eX- treme end and the bead, as indicated in Fig. l. I is a cushion or seat on the rod d', and at the end of the sleeve d.

In Fig. l the awning is represented as loW- ered, and when in this position the springs e e, by their retractive force, hold the sleeves against their seats or cushions; in other words, the extension-rods have their minimum length when they are in this horizontal or lowered position.

To raise or fold up the awning I draw downward, as heretofore, upon the cords F F, by which means the frame and canvas is swung or folded upward, as usual. After the frame has reached a vertical or nearly vertical position I continue to pull downward upon the cords, and by this means the sleeves d cl are drawn upward on the rods d d; in other words, the

IOO

extension-rods are thus extended vertically, and the awning is thereby further raised, so that its folds will not materially obstruct the light from entering the upper part of the window. I now tie the cords as usual. This further or vertical movement has heretofore been permitted by hinging the extension-rods to vertically-sliding lugs, said lugs sliding on vertical bars.

To lower the awning I untie the cords. The springs e e are now free to retract, and they draw the awning and frame downward with sufcient force to separate the folds, if they tend to cling to each other, and the initiatory movement is thus insured automatically. rIhe awning will then fallforward or outward until the extension -rods assume a horizontal or nearly horizontal position, and they will again then extend only their minimum lengths. It will be perceived that 'I have not made provision for extending them excepting when they are in or nearly in their vertical position. The beads G G prevent the tie-cords H I-I from slipping toward the outer end of the sleeve d, and the cushions I I prevent noise in case the sleeves and lugs strike together.

In order to indicate that structural variations or modifications may be made in the extension-rods without a substantial departure from the principle and scope of my invention, I have shown in Figs. 3 and 4t that each ofthe said rods may consist of only two parts. For example, the extension-rod there shown may be regarded or described as being substantially the equivalent of the rod d and sleeve d, made in onecontinuous part or piece, the spring e being externally arranged, and open in its normal or free condition, and bearing against the bead (or shoulder) G at one end, and against an upturned end, f', of the hinged arm corresponding to the arm d', the said arm having therein aslot, g, and the said rod passing freely through the said upturned end, and also having a headed extension or guide, h, entering the said slot.

It will be perceived that the modifications referred to consist, mainly, in minor features or details of construction, and that other mere modifications may be made without a departure from my invention.

The operation is the same in all cases, excepting that the spring, when employed as shown in Figs. 1 and 2 exerts a drawing force, and a' pushing force when employed as shown in Figs. 3 and 4.

When the awning-frames are comparatively long, several extensible extension-bars will be employed, in which case only two will properly be termed side bars.

I am aware that awnings have heretofore -had extensible extension-bars, and I do not therefore here intend to claim the same, broadly; but,

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An awning-frame in which the extensible extension bars or rods are combined with springs retaining the said bars or rods yieldingly at their minimum length, and with one or more cords for folding and extending the n said frame, substantially as-and for t-he purposes specified.

2. The combination, in an-awning, of the canvas and tie-cords H H with extensible extension bars or rods having beads G G on the sliding sections thereof, substantially as and for the purposes specified. i

3. rIhe combination, in an awning frame having extensible extension bars or rods, of thev lugs D D and the cushions I I, the said cushions being arranged on the hinged section of the said bars or rods and between the said lugs and the inner ends of the sliding sections of the said bars, substantially as and for the purposes specified.

In testimony that I claim the foregoing as my own I hereto affix my signature in presence of two witnesses.
